U Yong Nam, a section head at the Robotics Institute, has developed a manned omnidirectional vehicle for carrying books.
Controlled by a librarian, the vehicle moves in narrow corridors between large bookshelves with lots of books to find ordered books and carry them to a conveyor.
The vehicle consists of four omnidirectional wheels, reduction motors, dampers, a control panel, a book basket, a chair, and batteries. The control panel has a monitor, a joystick, and a tablet PC, so the librarian can monitor and control all the states of the vehicle on it.
The four omnidirectional wheels and four DC motors which drive every wheel independently are installed on the vehicle. Each wheel has dampers for safe travel.
The omnidirectional wheels rotate clockwise or counterclockwise according to operation commands and the vehicle moves to a designated position running forward, backward and laterally or turning on the spot.
The vehicle goes in three stages of velocity: 2m/s (first), 1.5m/s (second) and 1m/s (third).
The vehicle is useful in libraries or storehouses with narrow corridors.
